About Chart Generator
This bar chart generator uses Apache ECharts to render CSV or JSON data as bar charts locally. It supports customizable bar colors, axis labels, legend, gridlines, and animations. Data input accepts CSV (first row as categories) and JSON (categories and series fields). ECharts uses Canvas or SVG rendering, and charts export as PNG.
